Abstract
A method of calibration including placing an instrument on an arbitrary point and at an arbitrary rotational orientation on an ultrasonic probe, obtaining spatial coordinates of the instrument, obtaining spatial coordinates of three points on an external surface of the ultrasonic probe, and using the three points to define an ultrasonic image plane, obtaining spatial coordinates of a set of landmarks which have a known spatial relationship to the ultrasonic image plane, these landmarks defining a direction in which the ultrasonic probe is directed within the ultrasonic image plane, and obtaining spatial coordinates of a front point on a front facing surface of the ultrasonic probe, the front facing surface having a known relation with a reference axis of a scanning plane of the ultrasonic probe that defines where an ultrasonic image starts within the ultrasonic image plane.
